Nuclear transfer from cultured somatic cells enables precise genetic engineering in large animals, including gene knock-in and knock-out. This technology offers significant potential for biomedical and agricultural applications.

Area of Science:

  • Animal biotechnology
  • Reproductive biology
  • Genetics

Background:

  • Somatic cell nuclear transfer (SCNT) is a key technique for genetic modification in animals.
  • Precise genetic manipulation, including gene addition (knock-in) and inactivation (knock-out), is crucial for advancing animal science.
  • Cultured somatic cells offer advantages as genetic material donors in SCNT.

Purpose of the Study:

  • To review factors influencing embryo development in SCNT.
  • To discuss the benefits of using cultured cells for genetic material donation.
  • To explore methods for enhancing gene targeting efficiency in SCNT.

Main Methods:

  • Review of existing literature on somatic cell nuclear transfer.
  • Analysis of factors affecting SCNT embryo development.
